The Suspected Crimes of Guy Muldavin

When a girl walking on a Provincetown, Massachusetts beach discovered the decomposing body of a young woman in the summer of 1974, it began an investigation into what would become one of the most notorious cold cases in the state’s history. The victim—who would remain unidentified for nearly five decades—and her killer were the source of much speculation, with theories ranging from an extra in Jaws to the victim of the local mob.

After decades of mystery, DNA from the remains of “the Lady of the Dunes” was subject to extensive genetic matching and was finally identified as thirty-seven-year-old California resident Ruth Terry. A year later, authorities in Massachusetts announced their main suspect in the murder was Guy Muldavin, Terry’s husband at the time of her death. Muldavin died in 2002 and thus couldn’t be prosecuted for the crime, so the case was finally closed.

Identifying Ruth’s killer brought an end to one of the most enduring murder mysteries in Massachusetts, yet identifying the Lady of the Dunes and her killer turned out to the be the beginning of a new mystery. Indeed, investigators soon learned this might not have been Muldavin’s first murder, but one of several mysterious disappearances that traced back to him.
